Paddling with a very large dog 2014

I am looking for suggestions for a lightweight canoe that will carry my 125 lb. Newfoundland with me. Lake and slow river day trips or maybe an overnight. I will usually be solo.

(The last string I saw about this topic was in 2010 so this is the 2014 version.)

125 doesn’t seem so bad. And most
dogs learn to settle down after an initial period of chaos.
